Be it known that l.. lamine il. VAN .lNnicnN a citizen ot the ilnite'il .'tites. residing at 20G Sylvan itreet. Rutheiiird. in the count;7 of Bergen, .ltnteI ot len' .lersey, have. invent-ed certain nenv and iiseinl linprfwements in :l Ticket l-loist. oi which the Yfollowing' is e. hill., clear, concise. and cxzitt description.

This invention relates to a ticket hoist it'or use with c. mechanical ticket distributing` system. such is employed in telephone en# chai es for sending information or instructions troni one operator to aiiothei.

rlhe ohiect ot this inventien is to p'fox'ide e method sind Ineens whereby an :il'ticlc cerrier .may he started, hjf :in operrfitor. .troni :It position ineccessihle to the operator and maintained in motion thereafter without the attention of the operator.

The ticket hoist comprises a casing` which is attached to the main guides oit the ticket distributing' system. Pivotally Inonnted one end of the casing is s. shaft to which is fixed e. hoist arse and on Which is rote.g tnhly mounted :i cern Wheel Which nich-ef' engagement with the hoist erin. ln the other end ot' the casing; is e shaft te which two nearly parallel levers are fined. The lower end et one lever is connected to the pei'iphei-xi' oi' the cam `wheel hy of :t link consisting ot :i helical shrine' which hewnv tiene connected to each end. The. other lever `is connected to :i hell crank eine oneretincj lever. The moment about the shalt due to the weight oit' the hoist anni in certain positions hzilanced hy' the nioinent diie to the will on the cam Wl eel transmitted through the spi-inn'. l/ihen the hoist erin is in holizontel position. it is locl'ed in that position h); ineens oi" e doe' which. is pivote?. to the casing. The lowering' or saisine of the hoist arm is accomplished hy adjListing` the onerating' lever es 'to decrease or in- Acrease the nio lent about the @sin .fwis diie to the pull oi the spring; so that it either nnderhaliinces or over-helances the moment created hy the Weight oi the hoist erin. The cam Wheel is so designed that :is the hoist erin swings down up. the distance from the cem exis to the point through which the force exerted by the spring` acts, is decreased or increased so as to decrease or inmoment due to the spring. The the hoist erin from the dog is crease the release of effected when the operating lever is udjustci'l to alter the tension ot the shrine.

'llene QS is onnected to the Wheel le by e. screw .seninff nus l'Di-ojecting` thiongh the the lever is a rod 3l which is position and bracket 16. Fired to the axle 22 is a second lever 37 which has an opening therein. Projecting through the opening in the lever 3T is a rod 3S which has a thread portion 39 and a nut l() `thereon whicl'i connects the rod 8S to the lever 37. l'he other end ot the rolL 25S is connected to one arm ot a bell crank all which is pivotally mounted on the iframe of the guides 10 by means ot screv: The other arm oi' the bell crank el-l is connected to an operating lever all by means o1 rod L13. rllhe operatingv lever Ll-lconsists oit an oll'set rod mounted in bearings 4:5. rlw'o handles 116 and e7 are lixcd to the oilset rod, one to each end and they pro ject at right any; to the same.

i screw i8 projects through a bushing` Li9 which has an internal thread therein and which is fastened in the casing 13. Screw li8 serves to limit the movement oi the lever 23. Screw 50 projects through a` threaded openingin the bottom oi' the casing' 13 and serves to limit the down vard movement ol" the hoist arm 1T. lu bracket 16 is a set screw 5l which engages with member 52 which is made o'lf Jfeit or some substance which will der-.den the sound and which tends to prevent the rebound that would be caused by the coming` together oi two solid bodies. Member 52 is mounted on the casino; 13. By means ot screw 51 the horizontal position ot hoist arm 17' may be ad justed so as to force it into line witlrthe main guides 10.

A projection 53 integral with the cam wheel engages with the bracket 1G and serves to connect the two together. .sin adjustable screw 54: which engages with an internal thread in an opening through projection 53 is used to adjust the relative positions of cam 15 and bracket 16 so as to talie care of manufacturing.;- variations.

A spur guide mounted on the cass ing 13 so as to be in line with hoist arm 17 when it is in its horizontal position.

The eccentric screw nroiects throuejh one side of the casino; 13 land the doo'y 32. As the position ot the bracket 1G is altered relative to the main guides 10 by means of screw 51, the position oit the dog v32 may be altered by means ot the eccentric screw 34 so that the dog); 32 will always closely engage projection 35 when the hoist arm is in its horizontal position. The connecting rods 38 and 43 are so constructed that the distance between the members which they connect may be varied.

VAfter the device has been adjusted bv means of 'the adjusting screws mentioned.7 the operation oit the device is as follows:

lhen the hoist arm 17 `is in a horizontal I it is desired to lower it. the lever 4.4 is operated so as to raise rod 13. This relieves ythe pull on lever 37 and lever 23 which are fixed to the shaft 22. The

tension in spring 2T applied toV lever 23 causes shaft 22 to rotate until lever` 2S is stopped by set-screw 48. As lever 23 rotates, the tension in the spring 2T is reduced, and at the same time, rod 31 is forced in the direction oi dop androtates the same aboutfits axis so as to disengage it 'from projection and thus releases the hoist arm.V The reduction ot the tension olf spring;

about the asis 'of the shajtt ll so that thc positive moment created by the hoist arm overbalances it and consequently the-hoist arm descends.v Alter the hoist arm 1T, has passed through a small arc.y the moment created by the hoist arin about the axis ot the sha'lt 111 which is also the cam axis, decreases since the line through *which its weight acts due to the torce oi gravity moves toward the shat't 14. lWhen the hoist arm 17 descends, it rotates the cam wheel 15. As the cam wheel 15 rotates, the tension in spring 2'4" increases. At the same time, however, clue to they shape of cani wheel 15 the moment arm through which the torce oi the spring` 2T is applied to shaft 14, decreases 'last enough thatV the moment due to the 'spring is slightly less than the moment due to the hoist arm for a given arc of rotation. After the hoist arm 1T has passed through this arc in which the momentsare unbalanced. it reaches an arc in its path where the moments are again balanced due to the shape ot cam 15.

the hoist arm 17 has sui'iicient momentum arc of balanced moments, it will continue to the limit of its movement where it will be stopped by screw 50. Since its momentum decreases through this arc, it will not strike screw with any considerable Ytorce and the rebound will not be appreciable. li" the hoist arm is stopped anywhere in this arc where the momentsl are balanced it will remain in that position.

riter the hoist arm 17 is lowered. the ticket 2O inserted into the ticket holder 19. The lever le is then operated to draw down rodll which rotates the bell crank itl and through rod B8 revolves lever 3T which rotates shaft 22 and lever 23 thus increasing` the tension o't spring 2T.' This increases the moment about the cam axis created by the spring 27 and overbalances the moment created by the hoist arm 17. The hoist arm begins to ascend and ascends, the positive moment around the shaft 14- due to its weight increases, ililso. as the hoist arm ascends, the vcam wheel 15 rotates, and the point at which the tape 2S iizved to the cam wheel l5, ino-ves toward lever 23, thus decreasing' the tension oit spring 27. As the tension of spring 27 decreases, the `moment arm, through which it acts on shaft 14, increases enough so that the negative moment laround on reaching; this 2T decreases the nega-tivemoment as it,"

in length tast Leashes the siatt 14, due to the spriim` 2T., is always slightly more than the positive moment due to the weight oi the hoist alim l This causes said hoist arm 17 to ascend until set screw 51 engages With the telt stop When the hoist arm 1.7 is in its horizontal position. it this point. dogl 32 engages With projection on the bracket 1G and prevents any rebound which might occur it the moment developed by the springi- QT was enough greater than that due to the hoist arm 17, to throw7 screw 51 against member 59 with considerable torce.

After the hoist arm 1i' reaches its hor;i zontal position. the ticket 2O is f-arried along the hoist arm into the spur guide and then into one ot the main guides 10 by the trolley arm 21.
